One Killed, 3 Missing in Coast Guard Helicopter Crash

One U.S. Coast Guard crew member is dead and three are missing following a helicopter crash off of Alabama's coast on Tuesday night, officials said.

The helicopter crashed in Mobile Bay just after 8:30 p.m. local time southwest of Point Clear, and Coast Guard officials released a statement early Wednesday confirming the lone rescued crew member was found unresponsive. The crew member was later pronounced dead at a local hospital.

The search continues for the remaining three crew members at a crash site believed to be in about 13 feet of water. Their names have not been released pending notification of relatives.

Spokeswoman Petty Officer Second Class Elizabeth Bordelon, speaking from New Orleans, told Reuters Tuesday night the flight originated from the Aviation Training Center in Mobile. The cause of the crash remains under investigation.
